Proposal OutlineProposal Outline
Restoration of the Historic Leigh Street Armory
Construction of the New Office Building
Armory RestorationArmory Restoration Provide bracing to maintain historic façade Replace structural masonry system with a steel
moment frame load resisting system Install an open web steel joists floor system to support
the concrete floor slab Restore all masonry walls as non-structural elements Replace all doors and windows Install new steel roof truss system to maintain original
building aesthetics while improving structural integrity Comply with Current Code Requirements
Armory HistoryArmory History
Built in 1895
Served as headquarters for the First Battalion Virginia Volunteers Infantry, Richmond’s first African American regiment
Used as a social center, housing facility, recreation hall, elementary school, junior and high school

ConclusionConclusion
Efficiency– Our structure uses an intelligent moment frame
design coupled with a smart open webbed joist floor system.
Economical– This will minimize material cost, saving money.
The quick erection time shall reduce capital cost. Elegance
– Our Armory will maintain the authenticity of its historic fortress like appearance, and the New Building shall complement the aesthetic mastery of the Armory.
